• Key energy performance (KEP) of one fibrous filter and three ESPs are presented.
• KEPs of all ESPs are higher than that of fibrous filter.
• Newly developed ESPs have higher KEPs than their commercial counterparts.
• The parametric studies to KEP of ESPs are presented.
• Example of energy saving when fibrous filters are replaced with ESPs is presented.
Energy consumption of a filtration system depends largely on the pressure drop across the air ducts. The magnitude of this pressure drop is largely dependent on the presence of air filters designed to remove particles from the air stream. However, evaluating the performance of air filters by looking only at their pressure drop or collection efficiency is misleading because these two factors are not linearly dependent. A more rigorous approach uses key energy performance (KEP) to assess air filter performance, because KEP involves both collection efficiency and pressure drop. This paper provides methodology for the evaluation of performance of different types of filters, comparing the KEP of one fiber-based filter and three electrostatic precipitators (ESPs). One of the ESPs is commercially available, while the other two have novel particle-trapping mechanisms developed by our research group that substantially increase collection efficiency. The results show that, although all electrostatic precipitators have KEPs of at least nine times higher than fiber-based filters, newly developed electrostatic precipitators have KEPs of nearly twice as high as their commercially available counterparts. This paper also examines how three different operating conditions affect the KEPs of ESPs, and presents an example of energy savings in a filtration system when fiber-based filters are replaced with electrostatic precipitators.
